GAS-ENGINE GAS-SAVER AND CARBON-DECOMPOSER.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed January 22, 1917. Serial No. 143,612.

To all whom it may concern:

Be it known that I, ARTHUR E. GARBER, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Gas-Engine Gas-Savers and Carbon-Decomposers, of which the following is a specification.

My invention relates to an apparatus to be used in connection with gas engines for reducing the quantity of gas consumed and for reducing the carbon in the cylinders. The objects of my invention are: first, to provide a device of this class in which air may be introduced into the manifold and to the engine cylinders when the carbureter is shut off when using the compression of the engine for retarding the vehicle in going down hill; second, to provide a means for introducing varied quantities of water and hot air into the manifold above the carbureter for reducing the canbon therein, adding to the efliciency of the fuel mixture and reducing the quantity of gas consumed; third, to provide means for shutting off the water to the manifold when the carbureter is closed or when desired; fourth, to provide combined automatic means for, controlling the fiow of hot air and water to the manifold; and fifth, to provide an apparatus, of this class which is very simple and economical of construction, durable, easily installed and will not readily get out of order. I

With these and other objects in view as will appear hereinafter, my inventlon consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter described in detail andparticularly set forth in the'appended claim, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this specification in which:

Figure-1 is a diagrammatic View of my device complete. Fig. 2 is a s de elevational view of my valve mechanism. Fig. 3 is a top or plan view thereof. Fig. 4 is a detailed view of the hand control mechanism. Fig. 5 is a fragmentarvside elevational view of the exhaust manifold showing my heating device thereon. Fig. 6 is a transverse sectional view thereof. Fig. is a sectional view of mywater feed observation device. Fig. 8 is a front view thereof. Fig. 9 is a sectional v ew of the water ing, provided with an enlarged central portion 1* adapted for the valve 2 and with extended neck portions 1 and 1. The end 1 is threaded externally upon which is screwed a coupling 8 adapted for connecting the pipe 8 with the neck portion 1 of the valve casing. This valve casing is provided with a tapered hole in the center adapted for the valve 2 to fit into and close said hole. Extending each way are holes 1 and 1 to the ends of said valve casing the hole 1 connecting the valve 2 with the pipe 8 and the hole 1 connecting the'valve 2 with the nozzlel which is screwed into the end 1 of the valve casing. This neck 1 is externally threaded adapted to fit into a threaded hole in the manifold or in some cases into an L as shown in Fig. l and the other end of said L is screwed into the manifold above the carburetor. When the L is used as shown in Fig. l, the nozzle 1 is screwed into the L which is internally threaded for that purpose. The valve 2 is provided with a hole 2 conforming to' the hole 1 and on the opposite side said hole widens at 2 shown best in Fig. .11.

Mounted in said casing below the hole 1 is another hole 1 which extends from said valve to the outside of said casing so that when the valve 2 is turned in one direction the communication through the casing will be closed, when it is turned in the position shown in Fig. 2 of the drawing there is an open passage through said casing from the pipe 8 to the manifold. When it is turned in the opposite direction the communications through said valve will be closed but the hole 2 connecting the hole l with the hole 1 will be open allowing air from the outside to enter the manifold. The valve 2 is operated by means of a lug 2 to which is connected a rod 3 which extends to the hand control 3 and it connects with a lever 3 pivotally mounted on said hand control so that when the lever 3 is moved the valve 2 is revolved in said casing for opening and closing the valve and for allowing air from the outside to the manifold as desired. This rod 3 is preferably inclosed in a flexible casing 3. To the other end of the pipe 8 is connected the air and water heater 4: which consists of a metallic piece, shaped as shown best in Figs. 5 and 6 and on the inside is provided a corrugated wire netting, 4' adapted to support the same and prevent its being easily crushed from the outside and also to conduct the heat internally through said heater thus adding to its efficiency. At the other end of said heater is mounted the air intake and water mixer 6. This air intake and water mixer is a cup shaped device provided at its lower end with a neck 6 threaded externally adapted to screw into the internally threaded lug 4* on said heater. It is provided on one side with a hole 6 adapted for a pipe 6 which communicates with one side of the observation device 5. Mounted in the upper end of this cup 6 is a web shaped frame 6, the sides extended downwardly and forming a valve seat 6*, and mounted centrally therein is cylinder 6' in which is adapted to reciprocate the valve rod 6 upon the lower end of which is secured the valve 6. v Mounted on the upper end of this cylinder by means of threads is an adjustmg nut 6 and between it and the end of the rod 6 is a compression spring 6 which is adapted to keep the valve 6 seated. Mounted on the dash of the vehicle in sight of the operator is the observation device 5 which is a hollow casing provided with an inlet 5* and an outlet 5. In the side next to the operator it is provided with a glass 5 so that the operator can see whether or not water is dropping from the nozzle 5.

Communicating with the inlet 5 and its handle extending out through the front side is provided'a needle valve 5 adapted to close off'the water in the upper side of said observation 'device as desired. From the inlet 5 is provided a pipe 5 which communicates with. the tank 7 which is mounted in any suitable place inside of the hood of.

the vehicle. ,7

eashes when the carbureter and water and hot air valve is closed, that there is provided an eflicient means for heating both the air and water from the engine exhaust, that there 1s provided means for determining the quantity of water going to the manifold and for regulating and stopping the same, that the device is simple'and economical of construction, durable, easily installed and will not readily get out of order.

Having thus described my invention what I claim as new and desire to secure by Letters Patent:

In a device of the class described, the combination of a water supply tank, a combined water and air heater, means for conducting water from said water supply tank to said combined water and air heater, means for observing the quantity of water conducted and for regulatlng and stopping the same, means for automatically admitting air with said water to said combined water and air heater, means for conducting the heated water and air to the manifold of a gas engine, and means in connection with said last mentioned conducting means for shutting off the su ply of heated water and air to said manifo d and for simultaneously admitting air from the outside to said manifold with the stopping of said heated water and air supply.
